Look up a video in Shenzhen or Chongqing. Everything looks 2 decades out, and the giant crystal skyscrapers light up different colors. Sometimes the whole thing is a TV.
China surpassed USAmerica in GDP already, but it doesn't look close to tied in development and advanced technologies.
The trains there go hundreds of miles in less than an hour, you could commute across the country every day.
Meanwhile in America the "middle class" is struggling to have some walls and a roof. Record debt and crumbling infrastructure. How is all of this ignored and not talked about everywhere?
I don't see it explicitly done in this thread, but to build on your comment a bit, the "futuristic cities" are a result of the liberalization of the Chinese economy and should not be upheld as a socialist achievement while the inequality still exists imo. The best you could say is that "under a socialist government, you're not necessarily gonna be banned from doing cool shit while we work towards building a socialist economy".
